Chemical Structure

Tri-M-Cresyl Phosphate CAS 563-04-2 chemical structure

Description

Tri-M-Cresyl Phosphate (C21H21O4P) contains a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Tri-M-Cresyl Phosphate (CAS 563-04-2) is a high-purity analytical reference standard with the molecular formula C21H21O4P and a molecular weight of 368.36 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures Tri-M-Cresyl Phosphate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
